I RenewedMay 6, 1935 14 Claims.

This invention relates to devices for dispensing loose milk and particularly to the provision of a simple and compact form of attachment for a milk container by means of which the milk may 5 -be discharged therefrom in a simple., practical and foolproof manner; and the object of the invention is to provide a device of the class described in the form of acover part including means for supporting two tubes or pipes in conf nection therewith and to extend into the container, one of said means including means whereby a pressure element, such for example as nitrogen, may be introduced into the container through one of said tubes to agitate the milk in the container and to discharge the same through the othertube; a further object being to provide the last named tube or attaching means with a-manually controlled and operated member for controlling and regulating the discharge of milk from the container and by the operation thereof to regulate the amount of milk discharged; a further object being to provide a discharge spout detachably coupled with the cover part and tubeis discharged into a suitable container; a further object being to provide the cover with a recess or chamber in which the intake and discharge elements of the device are located and in which the dischargespout is normally positioned when not in use, and to the provision-of a cover for ysaid chamber with means for sealing the cover to prevent unauthorized tampering with the attachment; a further object being to provide a simple and yet strong and durable means for securing the cover part of the attachment to the container and to seal, the part thereon against unauthorized displacement; and-with these andY other objects in view, the invention consists in a dispensing device or attachment of the class described which is simple in construction, eflicient in use, and which is constructed as hereinafter described and claimed.

The invention is fully disclosed in the following ing forms a part, in which the separate parts of through which the milk from the second namedspecification, of which the accompanying drawis an important factor that the device as constructed have certain requirements to render it practical for use in the dispensing of loose milk, from the standpointl of maintaining proper standardization of the milk dispensed by the at- 5 tachment, to prevent or obviate the introduction' of water or other foreign elements into the container or the milk therein to dilute or otherwise change the characteristics thereof to provide, by agitation, the discharge of the required propor- 10 tions of butter fat in the quantities or amounts of milk intermittently discharged from the container, and further, to provide a device which by virtue of its design and construction, especially with respect to-that'partthereofwhich is ex- 15 posed to the interior of the milk container, may be readily cleaned to render thevvrsame sanitary during the continued anti repeated use thereof.

In the accompanyingI drawing, I have shown for the purpose of illustrating one method of 2 0 f carrying my invention into effect, an attachment consisting of a main body 5, which for the purpose of this 4description may be termed a cover part. This part consists of a central at wall portion of triangular'shape as viewed in plan, the 25 inner end being4 contracted and the outer end adjacent the periphery of the part 5 being flared and comparatively wide. Bordering the top '-.vall 6 Ais a vertical wall portion 1 which joins an outer -vertical wall portion 8 through a top wall 9, the 30 latter extending from the boundaries of the vertical wall 'I to the periphery of the vertical walls 8 of the part 5, the wall 9 being` comparatively narrow at the inner end ofthe w'all 6. A chamber I0 is formed in the part 5 above the wall 6 and 35 within the wall 1. It will appear that this struc-f, ture forms what might be termed a cup-shaped or disk-shaped casing, the central portion of which is depressed to form the chamber I0. The upper end of the wall 'I is grooved as seen at II 40 and also includes a tongue I2 which. ts in a corresponding grove I3 formed in a supplemental' cover part I4, the latter having a peripheral flange` I5 which enters the groove I I,` it being understood that the supplemental cover I4 is of a 45 contour consistent with that of the walls 6, 'I but tapering downwardly to the flared end as indicated in dotted lines in Fig. 2. The outer ared end of the supplemental cover terminates in a downwardly and outwardly flared end portion I 4a 50 whichis notched or recessed as"'se en at Mb to receive a key and sealing pin I6, which passes through an apertured ange portion llc, the pin being secured to the -top wall 6 at the peripheral edge thereof a1 .d having an aperture' above the 55 ange I4'o;to receive aconventional seal a. recessj I'9 formed .in -tongueor flange I2 and to retain said inner end I1, preventing unauthorized removal oi' the supplemental cover- I4. The inner end o f the supplemental c'over I4 includes a downwardlyand outwardly projectinghook-shaped lug I8, cooperating with the wall J1 adjacent the against displacement and prevent the removal of the supplemental cover I4 until the seal I1 is broken. It will be noted that the central portion of the supplemental cover I4 is depressed and the entirev cover is contained within the top wallfS of the main cover part 5 sothat lwhen the several cans or containers Zware placed pari;
